• logging problems for swing applications

  - by mengmenger

  what kind of logging frame work or API to use for swing applications which is used by multiple users in Unix. Is it possible to log all verbose/exception in one file per day or event one user one file per day? Since the user can open the same application with multiple instance. I also have another solution is to save the exceptions into database. But if I miss the excetpions, those will not be saved in DB. anybody has better solutions? Thank you very much!

• Applet JAR loading fails, since the http request doesn't include a basic auth header

  - by bowgene

  It's a farily simple setup. A .jar is hosted on a site which is protected by basic auth. I try to load the jar with an object tag - which works perfectly when tested without authentication. When the .jar is requested from the server, the basic auth header isn't included in the request. Why is this?

• Ubuntu terminal questions

  - by Camran

  I am wondering about my VPS providers ubuntu terminal. Are all these terminals the same? I think they are so user-UN-friendly. I can't copy-paste into the terminal, when I try opening textfiles, I can't scroll up and down easily. I cant save easily. Nothing is easy... Is it always like this with Ubuntu? Is there any way to make it easier? I use windows but I login to my vps provider with login details and then simply click "terminal" to open the terminal. Please help me out here

• j2ME setLocationListener()

  - by Jeff Catania

  I'm programming a GPS tracking system using the Motorola i335 running on Sprint's IDEN network. I'm using the javax.microedition.location api to find the GPS coordinates. To set up the updating, you use the [setLocationListener][1] method. I originally tried passing (listener,2,1,1). However there was too many invalid locations being received (where the GPS could not get the fix in the specified time), so I changed the parameters to (listener, 20, 20, 1). Now the system barely throws any invalid locations. My goal is to get the fastest number of updates that are realistic. Have any of you found a happy medium for parameters of this method?

• How to access private static target field in aspect in AspectJ?

  - by LihO

  I have a simple class Main with private static int x and an aspect that should output the old value of x before it is reassigned: public class Main { private static int x; public static void main(String[] args) { foo(7); } public static void foo(int y) { x = y; } } and MonitorX.aj: public aspect MonitorX { before() : set(static int Main.x){ System.out.println(Main.x); } } which doesn't work since I can't access private x using Main.x. I've also tried: before(int t) : set(static int Main.x) && target(t){ System.out.println(t); } which doesn't work either (nothing is outputted, if I try to output string, it seems that the aspect isn't invoked at all). However printing out the new value that is being assigned works: before(int newVal) : set(static int Main.x) && args(newVal){ System.out.println(newVal); } What am I missing?

• Is a HashMap thread-safe for different keys?

  If I have two multiple threads accessing a HashMap, but guarantee that they'll never be accessing the same key at the same time, could that still lead to a race condition?

• Do Hibernate table classes need to be Serializable?

  - by Scott Leis

  I have inherited a Websphere Portal project that uses Hibernate 3.0 to connect to a SQL Server database. There are about 130 Hibernate table classes in this project. They all implement Serializable. None of them declare a serialVersionUID field, so the Eclipse IDE shows a warning for all of these classes. Is there any actual need for these classes to implement Serializable? If so, is there any tool to add a generated serialVersionUID field to a large number of classes at once (just to make the warnings go away) ?

• What is the fastest way to learn JPA ?

  - by Jacques René Mesrine

  I'm looking for the best resources (books, frameworks, tutorials) that will help me get up to speed with JPA. I've been happily using iBatis/JDBC for my persistence needs, so I need resources that will hopefully provide comparable functions on how to do things. e.g. how to I set the isolation level for each transaction ? I know there might be 10 books on the topic, so hopefully, your recommendation could narrow down to the best 2 books. Should I start with OpenJPA or are there other opensource JPA frameworks to use ? P.S. Do suggest if I should learn JPA2 or JPA1 ? My goal ultimately is to be able to write a Google App Engine app (which uses JPA1). Thanks Jacque

• Redirecting the response from a filter throws an IllegalStateException

  - by Ritesh M Nayak

  I am writing a filter that will handle all authentication related tasks. My filter is a standard servlet filter as shown below @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { UserSession attribute = (UserSession)request.getSession().getAttribute("user_session_key"); if(attribute!=null && attribute.isValid()) { //proceed as usual, chain.doFilter(req, res); return; } else { //means the user is not authenticated, so we must redirect him/her to the login page ((HttpServletResponse)res).sendRedirect("loginpage"); return; } } But when I do this, I get an IllegalStateException thrown by Tomcat's ResponseFacade. How do I acheive this in a filter. I read in other SO threads that in TOmcat this is a problem as the response object is already commited. How do I get past this ?

• How to use a regular expression and assign the result to variables in Android?

  - by ChengYing

  I have a string named s_Result which will be parsed from the Internet. The format may be "Distance: 2.8km (about 9 mins)", and there are 4 variables which are f_Distance, m_DistanceUnit, f_timeEst, m_timeEstUnit. My question is how to parse s_Result and assign 2.8, km, 9, mins into f_Distance, m_distanceUnit, f_timeEst and m_timeEstUnit respectively using regular expression? I tried using "\d+(\.\d+)?" in RegEx Tester and the result showed 2 matches found, but if I use "\\d+(\\.\\d+)?" in Android code, it showed no matches! Any suggestions what might be going wrong?

• Attributes in XML subtree that belong to the parent

  - by Bart van Heukelom

  Say I have this XML <doc:document> <objects> <circle radius="10" doc:colour="red" /> <circle radius="20" doc:colour="blue" /> </objects> </doc:document> And this is how it is parsed (pseudo code): // class DocumentParser public Document parse(Element edoc) { doc = new Document(); doc.objects = ObjectsParser.parse(edoc.getChild("objects")); for ( ...?... ) { doc.objectColours.put(object, colour); } return doc; } ObjectsParser is responsible for parsing the objects bit, but is not and should not be aware of the existence of documents. However, in Document colours are associated with objects by use of a Map. What kind of pattern would you recommend to give the colour settings back to DocumentParser.parse from ObjectsParser.parse so it can associate it with the objects they belong to in a map? The alternative would be something like this: <doc:document> <objects> <circle id="1938" radius="10" /> <circle id="6398" radius="20" /> </objects> <doc:objectViewSettings> <doc:objectViewSetting object="1938" colour="red" /> <doc:objectViewSetting object="6398" colour="blue" /> </doc:objectViewSettings> </doc:document> Ugly!

• Bulding an multi-platform SWT application using Ant

  - by Mridang Agarwalla

  I'm writing an SWT application which can be used on Windows (32/64 bit) and Mac OSX (32/64 bit). Apart from the JRE I rely on the SWT library found here. I can find four versions of the SWT library depending upon my target platforms (as mentioned above). When building my application, how can I compile using the correct SWT Jar? If possible, I'd like to try and avoid hard-coding the Jar version, platform and architecture. The SWT Jars are named like this: swt-win32-x86_64.jar swt-win32-x86_32.jar swt-macosx-x86_32.jar swt-macosx-x86_64.jar (My project will be an open source project. I'd like people to be able to download the source and build it and therefore I've thought of including all the four versions of the SWT Jars in the source distribution. I hope this is the correct approach of publishing code relying on third-part libraries.) Thanks everyone.

• How do I integrate GUI elements from different classes at runtime?

  - by thefourthdoctor

  I'm trying to "future-proof" an application that I'm writing by splitting out those elements that are likely to change over time. In my application I need to be able to adapt to changes in the output format (e.g. today I output to a CSV file, in the future I may need to output directly to a SQL Server database, or to a web service, etc.). I'm handling this by defining an abstract class ("OutputProvider") that I will subclass for each individual case. The one aspect of this that has me stumped is how to provide a configuration GUI that is specific to each concrete class. I have a settings dialog with a tab for output configuration. On that tab I intend to provide a drop-down to select the provider and a JPanel beneath it to hold the contents of the provider-specific GUI. How do I get the right GUI in that panel at runtime and have it behave correctly with respect to events? Also, a bonus would be if there was a way to do this such that in order to add support for new providers I could simply provide a new jar or class file to be dropped in a specific folder and the application could pick that up at startup. I'm using NetBeans and Swing.

• How do you determine an acceptable response time for App Engine DB requests?

  - by qiq

  According to this discussion of Google App Engine on Hacker News, A DB (read) request takes over 100ms on the datastore. That's insane and unusable for about 90% of applications. How do you determine what is an acceptable response time for a DB read request? I have been using App Engine without noticing any issues with DB responsiveness. But, on the other hand, I'm not sure I would even know what to look for in that regard :)

• How to solve docbuiler saxexception: unexpected end of document?

  - by user211992

  I have a service that gives some car information in an xml format. <?xml version="1.0" encoding='UTF-8'?> <car> <id>5</id> <name>qwer</name> </car> <car> <id>6</id> <name>qwert</name> </car> Now the problem that I'm having is that my DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); Document doc = docBuilder.parse(xml); Sometimes throws a SAXException (sometimes it works just fine, but when I reboot the server (still in development) I sometimes keep getting it) with as cause SAXException: unexpected end of document. But when I place a bufferreader there to see what it's receiving and I copy the value into an xml document and I open it in firefox/ie it looks just fine.
